urriEn STATES CHARLES A. ROBBINS AND WILLIAM F. ROTH, OF NEVADA, OHIO.

WATER-HEATER.

To all whom it may concern:

Be it known that we, CHARLES A. ROBBINS and VILLLUI F. Horn, citizens of the United States, residing at Nevada, in the county of \Vyandot and State of Ohio, have invented certain new and useful Improvements in Water-Heaters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in water heaters and has for its object to provide a heater of novel and efficient construction embodying a plurality of water pipes having removable caps which, when removed, convert the water pipes into heating drums for heating air.

lVith this and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and'illustrated in the accompanying drawing, in Which:

Figure 1 represents a front elevation of the heater. Fig. 2 represents a vertical sectional view therethrough. Fig. 3 represents a horizontal sectional view on the line 3-3 of Fig. 2, and Fig. 4 represents a vertical sectional view taken at right angles to Fig. 3 and on the line 4f.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the hollow body of the stove, which is preferably of rectangular formation and supported above the floor upon legs 6. The bottom of the body 5 is formed with a plurality of perforations permitting air to have access thereto to sustain the flame from a burner 7 supported upon said bottom. While I have shoWn a gas burner arranged in the body 5, it will be understood that the construction of the latter may be varied to permit the use .of various other fuels. A plurality of vertically elongated flues or pipes 8 are arranged above the body 5 and communicate with the latter, and constitute smoke pipes and heating drums. The upper extremities of-the pipes 8 are extended into the opposite ends of a manifold 8 and the latter is connected with a pipe 9 adapted. to carry off the products of combustion from the heater. A horizontally disposed water pipe 10 is supported within the end walls of the body 5 Specification of Letters Patent.

in the water pipes is conducted to any desired point. The central portion of the horizontally disposed water pipe 10 is connected with a plurality of vertically dis posed water pipes 13, which latter are extended into and communicate with a chamber let-formed in the manifold 3 by partitions 14. Short vertical extensions 15 are formed on the manifold 8 and communicate with the chamber H and are suitably threaded to receive caps 16 having apertures therein for the reception of outlet pipes 17 for carrying off the water heated within the several water pipes 10, 13 and 14.

The fuel pipes 20 supplying the burner 7 with liquid or gaseous fuel is extended rearwardly and in close relation to the central vertical water pipe 13 and is provided therein with a valve 21 to the stem of which one end of a thermal coil 22 is secured, the opposite end of said thermal coil being anchored to a post or lug 23 carried by the central vertical water pipe 13, whereby when the water within the pipe 13 reaches a predetermined temperature, the thermal coil 22 expands and automatically closes the valve 21 and thus cuts off the flow of fuel to the burner 7. If desired, the valve 21 may be arranged in the fuel pipe 20 at a point adjacent the water pipe 12. v

In use, the heater may be used for heating Water by attaching the pipes 12 to suitable water supply pipes and connecting the outlet pipes 17 with any suitable device for utilizing the heated water, or the heater may be arranged in a hot water heating system for operating the system. If desired, the caps 11 and 16 may be removed and the heater employed for heating air, the pipes 10 and 13 being converted into air heating drums. hen the Water within the several pipes 10, 13 and 14 reaches a predetermined temperature, the thermal coil 22 opera es to automatically close the valve 21 and thus cut off the supply of fuel to the burner 7 through the fuel pipe 20.

What we claim is:

A device of the character described comprising a hollow body, a burner arranged within said body, a manifold arranged in arranged in said manifold dividing the latter into two chambers,

said horizontally disposed pipe,

a horizontally disposed imperforatepipe having open .ends' supported within and,1: ro e cting outwardly ofthe ends of said body, a plurality of Vertically disposed pipes commun cating w th upwardly through the top of. said removable caps closing saidextensions, re movable closures for the ends of. said horizontally disposed pipe,

I ma disposed a plurality of vertiand communicating withvthe other chamber in said nianifold-at'their upper ends, and a discharge pipe; connec ed: with :the second mentioned chamber ofsaidmanifold.

pipes communicating di. rcctly with said body at their lower ends,

- In testimony whereof We affix tour signatures in prles'ence of two Witnesses.
